  • Re: Communal Night-Sky Photography Thread

    That does look pretty complicated John, I can see why Mark is getting scared.
    I just looked back a few pages and saw the Cosmic Adventure video link that Dave posted. It's a great video and well worth a watch Mark to dispel some of those worries.

      It does look a bit scary but when you consider each bit works on its own it seems to come together. The problem is forgetting to do something in sequence.

      The setup has now been upgraded with an iOptron RC6 telescope giving 150mm aperture and 1370mm fl i.e. f9. Still using the OMD -EM1 MKII or OMD -EM5 MKII. There is no Olympus lens that can come anywhere near the field of view I can get with this telescope.

      This setup is fully goto I use Stellarium to sync and goto in the warm and comfort of my rear room. I only need to be outside to do the polar align. There is no guide scope either as the iOptron CEM25EC mount has encoders and I can get round stars at 8mins exposure.

      This is the Dumbbell Nebula M27 Its 1360 light years from Earth.

        Your new setup looks very nice indeed.
        Are you using a field flattener on the iOptron RC6
        Getting round stars for 8-minute exposures on the CEM25EC mount is amazing especially at 1370mm focal length

          No field flatter. I am trying to avoid glass in the imaging train. I did not use 8mins exposure on this one. I tried 8mins to see what it looked like. I have not tried guiding with this mount having looked extensively on the forums and decided to look at the end result and not try and test the mount and confuse myself even more.

          I am still experimenting with exposure times verses number of exposures.

            I know the issue it's very much a trial and learn approach. Have to say your shots so far look amazing. Using the Oly cameras on such a good mount and scope really does show what's possible with persistence.

            My scope is only 550mm fl so its more forgiving. I do use PHD2 guiding and have achieved 300secs exposures and even up to 500 secs with round stars on a good night.

            My next project is a nebula called SH2-101 which is very faint. I need (want) to get more than 15 lights at 600 secs exposures for each filter to get any really decent result so fingers crossed.

              John the gear and the astro images look amazing but so does the view from your garden. I'm hoping to move somewhere with a view soon but nothing like that, wow!

                Well, you have to start somewhere and with John's (birdboy) generous guidance I took my first Milky Way sequence of 17 shots last night.
                But browsing this communal thread I see that I am not even in astrophotography infancy; embryonic is my present state of development.


                So at 6:00pm I headed for the Warby Range lookout. From the car park it's a 700 metre uphill slog to the telco towers where I had a 2hr wait until 9:00pm when I began the first sequence.
                Killing time and taking advantage of the perfect view I shot a few selfies with the cellphone - couldn't believe that insect caught hovering above me!

                It is many months since I last visited this spot. I had visualised using the towers as a spacy looking foreground but had overlooked the ground level infrastructure that would mar the view.

                To eliminate most of the clutter I cameoed this unprocessed single image from RAW.

                The end to this story is that by 10pm when it was time to go home, I realised that I had forgotten my torch; no way known could I have found my way back to the car
                in pitch black darkness. There was just enough battery power in the phone to call my darling daughters who came to the rescue, arriving around 11pm to guide daddy home!

                  I saw an image of the Tulip Nebula in the Oct edition of Astronomy Now captured with narrowband filters. It was a wow as an image and as session he took a two-panel mosaic in the Hubble palette. He took 30 x 1200sec each in Ha S-II and O-III for both panels. If I understand this that's 60 hours at least without adding the calibration files. Clearly he had good access to clear night skies. His image did not look the same as what you get in Setllarium.

                  Good luck with yours and hoping for clear nights.

                    Sadly Phil it was only my back garden for a week. We stayed in a South Devon holiday cottage and I took my astro gear because of the potential for dark skies. Unfortunately Storm Lorenzo paid a visit that week as well and I only got 1 night of deep sky imaging done. I did get some milkyways between the clouds on another night.

                      The clear night challenge is always there for anyone in the UK. I can't stay awake much beyond 1:30 am so I need multiple nights to get a full image. With BST ending this weekend and it getting darker earlier I am hoping for longer runs.

                      I do get impatient with using narrow-band as the time needed is a lot longer than full colour. But it does allow you to image when the moons out which does help.

                      I have got the setup, polar alignment down to a few minutes now so at least I can actually do productive imaging a bit longer. Being able to control it from the warm indoors also makes a big difference.

                        I think that's an amazing image for your first time of trying Milkyway Mark. You picked a difficult choice of background to stack MW images. Wires and frames are very challenging for the advanced processing of Milkyway images for even the experienced MK tweaker. The single image framed as you have works for me. A stacked image should really bring out a even more vivid image of the MW.

                        If you get the chance again your landscape image would make an excellent background with the MW hovering in the sky.

                        What I find interesting is the way the MW appears to you in the sky down under i.e horizontal across the sky. For us in the UK at this time of year it appears vertical. I took this on the 29 Sep 2019.

                          I do not have the patience to do 3 or 5 passes with filters at the moment. I have tried a Ha filter on my OMD-EM1MII with no success. First I spent too long trying to get focus then DSS would not detect enough stars. I used 10 minutes exposure. I think if I use an dedicated tec cooled astro camera I could nail it as I can stretch the image in software and run longer times. So for now I will see what I can get with the Oly cam.

                            Now that's what I call a cameo Mark, great stuff. Glad you were rescued by the girls and got home OK, no doubt there was a bit of ribbing involved on the way home .

                              Yes Phill, ribbing there was with one daughter on each arm guiding the old man over boulers and rocks before reaching the road..
                              I haven't mentioned the farcical part. As I was packing up I realised the lens pouch to the 12-60 wan missing so the girls and I began trawling the area like a bunch of cops looking for a murder weapon. It was not to be found so I returned alone at 6am next morning but to no avail. Later that day I unpacked the backpack in which I'd carried the pod and found it scrunched up in the bottom. That's when the real ribbing started.
